To all whom it may concern:

Be it known that I, EDWARD R. Mnn'roN, a citizen of the United States, residing at Washington, in the Districtof Columbia, have invented certain new and use Improvements in Cooling Apparatus for Inking- Rollers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a device for cooling the inking mechanism of printing presses by means of air supplied thereto through suitable nozzles, and the object thereof is to provide improved air supplying means whereby air may be more effectively and conveniently applied to the inking mechanism than has been the case in former cooling mechanisms for the same purposes.

Inking mechanism for printing presses commonly comprises a plurality of rotary ink rollers which rotate in contact with one another, some of the rollers also frequently having a reciprocating movement transmitted to them so that they rotate in contact with other rollers and also partake of a transverse or sliding movement relatively thereto in order to secure a better distribu tion of the ink, the. result being that the rolls are unduly heated because of the friction between the rolls, and as the inking rollers are usually made of a plastic composition containing glue, they will be softened by the heat and will not carry the ink properly, with the result that good printing cannot be done. The heating of the inking rollers and their consequent softening also results in their being more rapidly worn away than when kept cool.

By the use of the device of my present invention not only is the heating of the inking rollers and their consequent softening prevented and the injury to the printing and rapid wearing away of the rollers prevented, but the paper lint caused by friction of the paper in, passing into the press is prevented from collecting on the rollers.

y lVhen this is allowed to take place the ink is rendered muddy, with a corresponding effect on the printin I have illustrated my invention in the accompanying drawings, described it in the following specification, and specifically claimed the same in the clauses of the 'coneluding claim.

In the drawings: Figure l is a side view showing my invention as applied to inking mechanism of a printing press; Fig. 2 is a plan view showing piping and nozzles for supplying air to the inking mechanism; Fig. 3 is a sectional view to further illustrate my device; and Figs. 4c and 5 are views showing details of my device.

In the drawings, 1 represents a portion of the frame of a printing press, and 2 is a part of the reciprocating type bed thereof upon which the type are carried and to which ink is to be applied.

3 is a bracket, one such being located at either side of the press, and which brackets serve as supports for the inking mecl'umism, the same being shown as comprising one or more rotary ink rollers at, 4, which supply ink to the type upon the type bed 2, and one or more ink rollers 5 which cooperate with the ink rollers atto secure a better dis tribution of the ink. As illustrated in the drawing, one roller such as 5, moves in contact with the two rollers 4-, although it will be understood that the mnnber and arrangement of the rollers which collectively form the inking mechanism of the printing press may be varied to suit the requirements of various types of presses.

6 is an air supply pipe located adjacent the inking mechanism and extending transverse to the press, one or more such pipes being provided, and the disposition thereof being dependent upon the features and type of the inking mechanism to be cooled. The pipe or pipes 6 are preferably supported in open top bearings 7 at the upper end of the brackets 3 as shown.

8 is a pipe leading from any suitable source of air under pressure and through which air for cooling the inking mechanism is supplied, such pipe being connected with the transverse pipes 6 by means of a swivel connection one form of which is shown at 9, Figs. 1 and 2, and which connection permits the pipe 6 to be swung upward and away from the inking mechanism when new rollers are to be supplied or when for other reasons it is required to have free access to the inking mechanism of the press.

The pipes 6 are provided with brackets 10, as many as may be found necessary and 11 are nozzles preferably curved at their ends as shown, carried by the brackets and each nozzle being adjustable relatively thereto either by being rotated within or by being moved longitudinally relatively to the bearings 12 which support them. The nozzles may also be adjusted as to inclination, by turning the bracket upon the pipe as an axle. From the above it will be understood that the nozzles are separately adjustable throughout extremely wide limits, and that streams of air issuing from them may be directed in a multitude of directions and in various ways upon the inking mechanism to be cooled, according to the type and requirements of the inking mechanism. Set screws 13 are provided for securing the parts in whatever position they may be.plaoed. Nipples 1d are carried by the pipes 6, and 15 are flexible conduits, one for each nozzle 11, connecting the nipples and nozzles and through which air may flow from within the pipe 6 of the several nozzles, the flexible character of the conduits permitting the adjustment of the nozzles above referred to. Each pipe 6 is also preferably provided with a valve 16 for regulating or arresting the flow of air through it.

Such being the construction of my device, it will be seen that a plurality of separate streams of air may be discharged from the several nozzles against the inking mechanism; and that the nozzles may be adjusted, each independent of the others, in order to direct the streams in various ways upon the inking mechanism. The fact that the brackets are rotatable about the air supply permits independent angular adjustment of the nozzles about the pipe, the capability of the longitudinal movement of the brackets upon the air supply pipe provides for independent longitudinal adjustment of the nozzles, and a further control of the direction of the stream of air is made possible because of the fact that the nozzles themselves are adjustable both about their axes and longitudinally, within their bearings 12- of the brackets. Finally the air supply pipe as a whole, together with the nozzles which it carries, may be swung up and away from the inking mechanism, this being permitted by the swivel connection 9.

Having thus described my invention and explained the operation thereof, I claim and desire to secure by Letters Patent:

1. In a cooling device for the inking mechanism of printing presses, an air pipe located adjacent the inking mechanism and extending transverse to the press; means through which air under pressure is supplied to said pipe; a plurality of nozzles adapted to direct streams of air against the inking mechanism and each of which is adjustable to thereby vary the direction taken by a stream of air issuing therefrom; and a connection between each nozzle and said pipe and through which air may flow from said pipe to each of said nozzles.

2. In a cooling device for the inking mechanism of printing presses, an air supply pipe located adjacent the inking mechanism and extending transverse to the press; means through which air under pressure is supplied to said pipe; a plurality of nozzles carried by said pipe and adapted to direct streams of air against the inking mechanism and each of which is adjustable relative to said pipe to thereby vary the direction taken by a stream of air issuing therefrom; and a flexible conduit communicating with the interior of said pipe and with each of said nozzles and through which air may flow from said pipe to each of said nozzles.

3. In a cooling device for the inking mechanism of printing presses, an air supply pipe located adjacent the inking mechanism and extending transverse to the press; means through which air under pressure is supplied to said pipe; a plurality of brackets upon said pipe and adjustable longitudinally thereof; a nozzle carried by each of said brackets and adapted to direct a stream of air against the inking mechanism; and a flexible conduit for each nozzle, the same communicating with the interior of said pipe and with its nozzle and through which air may flow from said pipe to each of said nozzles.

4:. In a cooling device for the inking mechanism of printing presses, an air su ply pipe located adjacent the inking mec anism and extending transverse to the press; means through which air under pressure is supplied to said pipe; a plurality of brackets upon said pipe and adjustable longitudinally thereof, and adjustable also angularly with reference to said pipe; anozzle carried by each of said brackets and adapted to direct a stream of air against the inking mechanism; and a flexible conduit for each nozzle, the same communicating with the interior of said pipe and with its nozzle and through which air may flow from said pipe to each of said nozzles.

5. In a cooling device for the inking m ss support them; and a flexible conduit for each nozzle, the same communicatlng with the interior of said pipe and with its nozzle 15 and through which air may flow from said pipe to each of said nozzles.

In testimony whereof I afiiX my signature in presence of two witnesses.
